Recent interferometric observations of the brightest and angularly largest classical Cepheid, l Carinae, with ESO's Very Large Telescope Interferometer have resolved with high precision the variation of its angular diameter with phase. We compare the measured angular diameter curve to the one that we derive by an application of the...

The projection factor (p-factor) is an essential component of the classical Baade-Wesselink (BW) technique, which is commonly used to determine the distances to pulsating stars. It is a multiplicative parameter used to convert radial velocities into pulsational velocities. As the BW distances are linearly proportional to the p-factor, its...

Now that large databases of resolved galaxy images are provided by modern imaging surveys, advanced morphological studies can be envisioned, urging for well defined calibration samples. We present the EFIGI catalogue, a multiwavelength database specifically designed for a dense sampling of all Hubble types. The catalogue merges data from...
